preparation example Construction

[0049] A short-process preparation method for TA5 titanium alloy medium-thick plates for ships, comprising the following steps:

[0050] Step 1, slab selection: take the TA5 titanium alloy slab, and define the length of the TA5 titanium alloy slab as , the width of the TA5 titanium alloy slab is , the thickness of TA5 titanium alloy slab is , the size of TA5 titanium alloy slab meets the following standards:

[0051] (1)

[0052] (2)

[0053] Among them, mm in the formula (1) is the length unit millimeter, and in the formula (2) is the thickness of the finished TA5 titanium alloy plate;

[0054] Step 2. Inspection slab: inspect the TA5 titanium alloy slab obtained in step 1: define the bad margin of the finished TA5 titanium alloy sheet as ;

[0055] (3)

[0056] In formula (3) are respectively the thickness, width and length dimensions of the TA5 titanium alloy slab determined in step 1, are the thickness, width and length of the finished TA5 titaniu...

example 1

[0087] First, check and select the slab: according to the finished product specification (20*1000*3000 / 1) and the requirement of the expansion deformation, the expansion deformation is selected as 15%, and the slab is selected as 130*900 according to the formula required for the selection of the slab *1030 specification slab, and widen the width of the slab (900).

[0088] Continuing from the previous step, widening and reversing rolling: ℃, rolling temperature Set to 1020°C. The widening passes are completed in two passes, and the deformation rates of the passes are 7.0% and 8.0% respectively. Then turn the billet 90° and carry out reversing rolling. After the reversing, the rolling is divided into 8 passes, and the pass deformation rates are respectively 17.1%, 18.4%, 17.3%, 19.3%, 20.0%, 20.0%, 20.3% , 19.6%. The total deformation rate of broadening and reversing rolling is 85%, and the final rolling temperature is 910°C.

[0093] First, check and select the slab: According to the finished product specification (22*1000*3000 / 1) and the requirement of the expansion deformation, the expansion deformation is selected as 10%, and the slab 130*800 is selected according to the formula required for the selection of the slab *960 specification slab, and widen the length of the slab (960).

[0094] Continuing from the previous step, widening and reversing rolling: ℃, rolling temperature Set to 980°C. The widening passes are completed in two passes, and the deformation rates of the passes are 4.0% and 6.0%, respectively. Then turn the billet 90° and carry out reversing rolling. After the reversing, the rolling is divided into 8 passes, and the pass deformation rates are respectively 17.1%, 20.4%, 20.3%, 20.3%, 19.0%, 19.0%, 18.3% , 17.6%. The total deformation rate of broadening and reversing rolling is 83%, and the final rolling temperature is 780°C.

Abstract

A short-process preparation method of TA5 titanium alloy medium-thick plate for ships, which adopts the whole-process process design concept, and comprehensively controls the edge of TA5 medium-thick plate from the aspects of slab selection, widening and reversing rolling, heat treatment process design, etc. Cracks, plate shape, structure and performance, the slab used in the production of medium and thick plates by this method is small, the production is convenient and flexible, and the requirements for equipment capacity are low.

Description

technical field [0001] The invention relates to a method for preparing plates, in particular to a short-process preparation method for TA5 titanium alloy medium-thick plates for ships. Background technique [0002] Titanium and titanium alloys have excellent properties such as high strength, heat resistance, and corrosion resistance, so they are widely used in aviation, chemical industry, and marine engineering. The nominal composition of TA5 titanium alloy is Ti-4Al-0.005B, which is a full α-type titanium alloy. TA5 titanium alloy has good welding and corrosion resistance, and can be used as structural material in seawater corrosion environment, and has been successfully used in shipbuilding industry. [0003] The aluminum equivalent of TA5 is 5.0, which is a single-phase hexagonal close-packed structure (HCP). Compared with the structure of face-centered cubic (FCC) and body-centered cubic (BCC), it has fewer slip systems and poor plasticity. Easy to crack. In particula...
